Those who watch Girls and The Mindy Project will be getting a double-dose of Allison Williams this week. The actor who plays Marnie, one of the "girls" in Lena Dunham's HBO comedy, is set to appear in The Mindy Project this Tuesday. A new video has arrived, which gives us a look at Williams' character, and some behind-the-scenes peeks at the making of the episode.

TVLine shared the video below, which previews The Mindy Project's upcoming "Bunk Bed," the first of multiple episodes in which Allison Williams will appear, playing a love interest to Dr. Castellano (Chris Messina). She also has an eye patch, which plays a part in how her path crosses with the doctor, but doesn't manage to do much in making her any less gorgeous than she is.

In addition to snippets from the episode and filming it, star/creator Mindy Kaling, Chris Messina and Williams herself all share some thoughts on what's going on in the episode and how it's been working together on the comedy.

So it seems Williams' character and Castellano are going to hit it off. She clearly has her eye on him, anyway. That joke was weak, but unavoidable.

The Mindy Project's "Bunk Bed" episode airs Tuesday, January 15 at 9:30 p.m. ET. And in case you weren't aware, Girls returns for Season 2 on Sunday, January 13 at 9:00 p.m.
